That's actually incorrect. A company can break even forever. In fact, you could arguably even lose small amounts of money for a very, very long time. It's not like workers aren't being paid and revenue isn't being generated. The stock would collapse, but the company wouldn't have to disappear.

Tesla cannot lose hundreds of millions or billions of dollars forever, but it could lose 10s of millions for decades. Elon Musk alone could fund those kind of losses for a very, very long time.

Hell, is Tesla shrunk it's loss to even $100M over the next year, the stock would probably skyrocket on another decade of hope.

That’s precious...you explaining equity pricing to me.  

Tesla is not immune to the market forces that determine its market capitalization.  Tesla’s discounted future free cash flows is its enterprise value.  Enterprise value is debt plus equity minus cash, hence if that expected future free cash mapping changes the equity price will adjust.  Note that additional debt loads will impact the value of its equity.   Once the institutional investors pull out, it becomes more difficult for Tesla to raise needed additional capital.
